LABOUR has launched a stinging attack on Deputy Prime Minister Nick Clegg, labelling him the "un-credible shrinking man" in a new party political broadcast to be aired tonight.

The video, which uses actors to portray a coalition cabinet meeting, sees the Lib Dem leader physically shrinking as he agrees with Conservative polices which go against his 2010 general election manifesto.

These include raising tuition fees and cutting the higher rate of tax.

The broadcast, to be shown this evening, is a pastiche of 1950s 'B' movies, specifically 'The Incredible Shrinking Man'.

While it attacks the coalition government, the clip fails to mention the upcoming European elections - or any Labour policies.

Michael Dugher MP, Labour Vice-Chair and Shadow Minister for the Cabinet Office, said: "You can't trust a word Nick Clegg says. Scratch the surface and Nick Clegg and the Liberal Democrats have a record of broken promises and propping up the Tory-led Government.

"While the Lib Dems have been in power, they have helped to deliver a trebling of tuition fees, a tax cut for millionaires and the hated bedroom tax while hard-working families across Britain suffer a cost-of living crisis.

"People across Britain are all being let down by Clegg selling out to Cameron.

"Labour will be campaigning online and on the doorstep in every corner of the country to expose the Lib Dems' failures in office and to hold them to account for betrayal".

Watch the Labour PPB and then tell me this is a political party serious about forming the next government."

But within minutes of the video being made available on YouTube, political commentators were denouncing the clip.

Telegraph and Total Politics writer Dan Hodges said: "Watch the Labour PPB and then tell me this is a political party serious about forming the next government."

Even LabourList website editor Mark Ferguson said the video lacked a "positive agenda" and tweeted "squeezing the Lib Dem vote when they’re already in single digits makes no sense".

Benedict Pringle, author of politicaladvertising.co.uk, described the tone of the advert as "as very sneering and slightly mean-spirited".

He said: "Obviously they’re trying to attribute those values to the Tories, but I think it’s backfired.

"It feels like Labour Party are being disdainful, arrogant and condescending towards Clegg and the Lib Dems.

The preposterous portrayal of the Conservative Party as old-fashioned toffs just doesn’t ring true.

"Whilst lots of people will disagree with Tory policies, I don’t think many people will find the characterisation of the Tory’s in this video fair or realistic."

He added: "I’m amazed it got signed off by the famously conservative Labour Party command.

"I would have thought the bit in the script where it says 'We see a miniature, naked Nick Clegg being chased down the Cabinet table by a cat' would have set off some alarm bells in the leadership’s heads."
